Thanks Flagg...I appreciate the input. Found a deal on two horizontal reflectors so obviously I'll be sure to get the correct U bulbs for them.

It was a phillips master color. It still works but it bothers me that the glass can move a half inch each direction. I put my 3100 back in with a mix of 4k QB and 3500 timber in the 4 x 4. The girls are loving it
Maybe the puny bulb was not made for my hulk hands or something.

That is SPD of two different bulbs at different power. You can see the difference. From feedback from our customers, it is still true.

I see.
But I will stick to the Phillips 3100 for now. I will have a better feel after I do the run in the 3x3 I just started.
Used open in my room I was disappointed compared to the 600 Hortilux super hps alongside.
It was more powerful than a 400 hps though.
Together they were great.
But I expect 2-3 feet thick canopy of buds as I grow bushes to stay in plant count. The 315 cant flower as effectively so deep into the canopy.

Overall, horizontal CMH reflector is better than vertical. The mail reason is that light bouncing many times inside a reflector loses much energy and gives off more heat. Also vertical reflector wastes more vertical space.
The keys to select a good 315W CMH reflector are:
1. Is the reflector correctly designed for 315W CMH bulb?
2. Can the light from the reflector cover a certain area such as 3x3 evenly at a certain height such as 2 feet?
3. Does the reflective material have higher reflective rate with different light (UV, blue, red, etc), not just with red light?

If possible, buy Philips 315W CDM bulb, much higher quality than any others.

According to Phillips the bulb is supposed to be mounted open and vertical.
These reflectors are designed to maximize the relatively low power bulb.
And according to the university of Utah that setup with the 3100k bulb is the best single light source for full plant growth.
And growers house shows highest par that way.
And I wish I had the commercial test I found last year but it is gone with my old phone. It showed highest par under the sun system vertical reflector at 16” over. 2.5’ x2.5’ area.
All I am hearing from you sir is opinions and customer comments.

Thanks Sunplix,
I picked up a couple of the Daystar units (non AC) and they'll be mounted on a light mover. One on each side of an LED I picked up. They're fairly deep but narrow and fit my needs perfectly. They have an internal ventilation system and if needed a flange can be added.
Any opinions on the mogul base Philips cdm 315s?

Philips mogul base 315W bulb (ED37) is 4k. I prefer T9, T12.

Yup. I just mean treat it serious. I feel i am getring tanned with my single 315.when i delarf and top
Running them at 400 is interesting.
And i think the loose glass case has not effected the 942 bulb.
The 3100 is a rockstar start to finish. For the size you have to get fancy to beat it.

Running the 942 at 400 is a complete spectrum. Very interesting.
Problem is i have lights for 4 x 8 and a 4 x 4 tent.
Kijiji. No way. My next house i will rock a 4 plant limit a veg tent and u2 big flower tents. 1 cmh and one quantum.
My problem is i bought another light. Happens a lot.
